Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Obsolete Part Replacement):

RG2012P-112-B-T5 (Susumu) serves as the primary direct equivalent. This part maintains identical resistance, tolerance, temperature coefficient, and operating temperature range. The RG2012P-112-B-T5 is manufactured by the same supplier (Susumu) and carries active product status, ensuring long-term availability. The power rating is reduced to 0.125W (1/8W); this substitution is valid only for applications where the circuit power dissipation does not exceed 0.125W. The part is ROHS3 compliant and includes automotive AEC-Q200 qualification, providing enhanced reliability for demanding environments.

Equivalent with Identical Power Rating:

RP73PF2A1K1BTDF (TE Connectivity Passive Product) matches the original 0.25W power rating and maintains all critical electrical parameters. This part is manufactured by TE Connectivity and carries active product status. The physical dimensions are within acceptable tolerance for 0805 package applications. ROHS3 compliance is confirmed. This option is suitable for applications requiring the original 0.25W power specification without supplier dependency on Susumu.

Higher Power Rating Alternatives (Upgrade Options):

PHP00805E1101BST1 and PHP00805E1101BBT1 (Vishay Dale Thin Film) both provide 0.63W (5/8W) power rating, representing an upgrade from the original 0.25W specification. Both parts maintain all electrical parameters and operate across the identical temperature range. PHP00805E1101BST1 is ROHS3 compliant and carries active product status, making it the preferred upgrade option. PHP00805E1101BBT1 is RoHS non-compliant and should be selected only when regulatory requirements do not mandate ROHS3 compliance. Both Vishay parts include flame proof and moisture resistant features, providing enhanced safety characteristics. The increased physical height (0.033" vs. 0.020") must be verified for PCB layout compatibility.

Selection Criteria Summary:

• For direct replacement with reduced power tolerance: RG2012P-112-B-T5
• For equivalent power rating with alternative supplier: RP73PF2A1K1BTDF
• For upgraded power rating with enhanced safety: PHP00805E1101BST1
• For non-compliant applications requiring upgrade: PHP00805E1101BBT1

Frequently Asked Questions (FAQ)

Q: Can RG2012P-112-B-T5 replace RGH2012-2E-P-112-B in all applications?

A: RG2012P-112-B-T5 is a direct electrical equivalent with one critical difference: the power rating is reduced from 0.25W to 0.125W. Substitution is valid only when the actual power dissipation in the circuit does not exceed 0.125W. If the circuit requires the full 0.25W capability, this part is not suitable. Verify circuit power calculations before selection.

Q: What is the difference between PHP00805E1101BST1 and PHP00805E1101BBT1?

A: Both parts are identical in electrical specifications and physical dimensions. The primary difference is RoHS compliance: PHP00805E1101BST1 is ROHS3 compliant, while PHP00805E1101BBT1 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, PHP00805E1101BST1 is the correct selection. Both parts feature flame proof and moisture resistant construction.

Q: Are the physical dimensions of substitute parts compatible with the original PCB layout?

A: The Susumu RG2012P-112-B-T5 and TE Connectivity RP73PF2A1K1BTDF maintain the standard 0805 package footprint and are directly compatible with existing PCB layouts. The Vishay PHP series parts (PHP00805E1101BST1 and PHP00805E1101BBT1) have slightly larger dimensions and increased seated height (0.033" vs. 0.020"). While the footprint remains 0805 compatible, the increased height may affect clearance in densely populated boards. Verify PCB layout clearances before selection.

Q: Why is RGH2012-2E-P-112-B classified as obsolete?

A: The RGH2012-2E-P-112-B is an obsolete product from Susumu's RGH series. Active alternatives from the same manufacturer (RG series) and other suppliers (TE Connectivity, Vishay) are available with equivalent or superior specifications. Obsolete classification indicates the part is no longer in active production; existing inventory may be limited.

Q: Can I use a higher power-rated substitute in place of the original 0.25W part?

A: Yes. The PHP00805E1101BST1 and PHP00805E1101BBT1 with 0.63W rating are suitable upgrades. Higher power ratings provide additional thermal margin and do not negatively impact circuit performance. However, verify that the increased physical height (0.033" vs. 0.020") does not create clearance issues on the PCB.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All substitute parts listed maintain MSL 1 rating, ensuring compatibility with standard component storage and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: No. RG2012P-112-B-T5, RP73PF2A1K1BTDF, and PHP00805E1101BST1 are ROHS3 compliant. PHP00805E1101BBT1 is RoHS non-compliant. For applications requiring ROHS3 compliance, select from the three compliant options.

Q: Does RG2012P-112-B-T5 include automotive qualification?

A: Yes. RG2012P-112-B-T5 carries AEC-Q200 automotive qualification, indicating it meets automotive industry reliability standards. This qualification is not present in the original RGH2012-2E-P-112-B or other substitute options listed.
